3. Splicing pigtails
Prepare the cable according to one of the drawings in 3.1. If you need longer
fibre ends, add 33 cm for an extra loop. If direct termination, use 70 cm for all
fibres

Cut pigtails to lengths 70 cm (fibres 1

Splice one fibre at a time, coil and mount them to the splice holder. Fibres

6 is mounted according to letter A and the red fibre on the drawing, fibres
7
-
12 is coiled half a turn more before mounting to splice holder. All coiling is
made in the same direction (counter
-
clockwise) to ensure proper bend radii.
Make connectors point out through the back (underneath the entering cable)
on the last turn and connect them to the adapter front there.
When all fibres are spliced, turn the adapter front around to the front and
attach it to the closure (B). Push it in from the front so that the fibre clamp
also is pushed in. Insert blind plugs in all unused holes. Raise the tip of the
rear fibre clamp (C) and mount the lid/back wall.
Detach the lid/back wall using a Torx 10 screwdriver.
Put on the appropriate numbering tab (depends on type of adapter), see
drawing 3.2. Install adapters.
Detach the adapter front and put it aside.

Install fibre guides (A), splice holder (B)
and fibre clamps (C).
Put the left fibre clamp partially under
the low sloping wall.
If cable diameter is below 5 mm, increase the diameter using crimp sleeve(s)
of 7 cm length (placed so it ends up inside the cable gland)
Put the cable through the cable gland, the strain relief unit and the nut, and
mount together. Secure the cable using tie

wraps.
